[Quickfix-developers] Requesting Previous Messages

[Karl S. <ka...@gm...>]

I am trying to use the store attached to a particular session in order to
request historical messages by the sequence number. I am running the C#
wrapper to quickfix and am requesting the previous message with the
following code:

int seqNum = (int)lvFixMessages.SelectedItems[0].Tag;
ArrayList msgList = new ArrayList();
FixApplication.Session.getStore().get(seqNum, seqNum, msgList);
if(msgList.Count > 0)
{
    QuickFix.Message msg = new Message((string)msgList[0]);
}

I may be running into a multi-threaded issue here, as this is called from
the user interface thread, but I was hoping that read operations were
threadsafe.

The problem is characterisitic of multi-threading issues, sometimes it works
just fine. Other times I get an AccessViolationException "Attempted to read
or write protected memory. This is often an indication that other memory is
corrupt."

Or sometimes I also get "Runtime Error! R6025 - pure virtual function call"

Please let me know if there is a threadsafe way to access the filestore. I
am using a filestore and a single initiator, with a standard Application.

Thanks,

-Karl
